Abstract

While adaptive control has been used in numerous applications to achieve system performance without excessive reliance on dynamical system models, the necessity of high-gain learning rates for safety-critical systems to achieve fast adaptation can be a serious limitation of most adaptive controllers. In order to address this problem, two novel adaptive control approaches developed recently aim to limit the bandwidth of the closed-loop adaptive control system in order to suppress the high-frequency content contained in the system error dynamics and adaptation algorithms. Specifically, this key feature of these frameworks allows for robust and fast adaptation by utilizing high-gain learning rates without inducing high-frequency oscillations in system states and the adaptive control signal. In this paper, we apply these two methods to a high-fidelity scaled transport aircraft model, namely the generic transport model, developed at NASA Langley Research Center in the presence of unexpected structural damage and uncertainty in control surface effectiveness.
